7400-GPS Option for the Ultimate Precision Reference
For the ultimate in precision, the 7400-GPS option can be used with the 7400 and 9400 modules. The
purpose of this GPS option is to provide an extremely precise frequency reference. The oscillator on
the 7400-GPS is more accurate than a typical internal precision standard and is equivalent in accuracy
to an atomic standard. Increased frequency accuracy makes it possible to frame synchronize signals
between different facilities with virtually no dropped or doubled frames. The GPS option also provides
precise time of day information, which can be used to drive the 7400 or 9400 module’s internal
timecode generators.
The 7400-GPS option seamlessly integrates into the Avenue system by plugging directly onto the 7400
and 9400 modules. It can be easily installed in the field. The 7400-GPS option consists of a compact,
weatherproof antenna (with internal high-gain pre-amp) and a receiver sub module which mounts
directly to the 7400 or 9400 module. The included GPS antenna mounts onto standard 3/4” threaded
pipe, metal or plastic. Connection from the F-style coaxial fitting on the antenna to the appropriate
BNC on the Avenue Frame can be made with customer supplied standard 75 ohm cable. The coax
cable can be routed through the center of the pipe for a completely waterproof installation. When low
loss cable such as Belden 1694A is used, the antenna can be placed up to 200 feet (60 meters) from the
frame. Ideally, the antenna is mounted outdoors where it has an unobstructed view of the sky.
For your reference a functional block diagram for the 7400 and 9400 follows, first as a portrait view and
then as a full page landscape view.
